Nielsen, Twitter, Team Up For New Rating

Twitter and Nielsen have partnered to create a "'Nielsen Twitter TV Rating' that will measure the total audience for social TV activity on Twitter, including both people who comment and
people who are exposed to their comments," writes Nat Ives. This metric will "act as a complement and companion to the Nielsen TV rating," helping to measure audience engagement with TV programming,
according to Chloe Sladden, VP-media at Twitter.
